Windows not activated after clean install

Once you’ve upgraded to Windows 10 using the free upgrade offer or Media Creation Tool on an activated Windows 7 or 8.1 PC, you will be able to reinstall, including a clean install, on the same device. You won’t need a product key for re-activations on the same hardware. If you make a meaningful change to your hardware, you may need to contact customer support to help with activation. You’ll also be able to create your own installation media like a USB drive or DVD, and use that to upgrade your device or reinstall after you’ve upgraded.

I did exactly this. I upgraded from a windows 7 pro system and everything went fine. Windows 10 activated. Since I am evaluating this for future company use I then burned a ISO DVD and did a clean install. That went fine also however Windows will not activate now. I called Tech support and they said to wait for an update and then it will reactivate. I just did one and still not active. How long do we need to wait? should I roll back to 7 pro and reinstall?
